Funerals (Al-Janaa'iz)
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ هِشَامٍ، حَدَّثَنِي أَبِي، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كُفِّنَ فِي ثَلاَثَةِ أَثْوَابٍ، لَيْسَ فِيهَا قَمِيصٌ وَلاَ عِمَامَةٌ.Narrated `Aisha:Allah's Messenger (ﷺ) was shrouded in three pieces of cloth and neither a shirt nor a turban were used
From Sahih al-Bukhari, whose reports the scholars accept as authentic.
